The right (passenger) rear tired had 4 punctures. It was irrepairable. Since the tread reading for the tires was at 5/32, I went ahead and replace all four. The last time I replaced them was in December 2019. Thanks to this blog, I could pull up the information immediately. The tires were over 3 years; therefore, they needed to be replaced anyway. I ordered 4 new all-season Michelin Defenders at Costco. I needed new tires so I can go to the ski resorts this coming winter.
Tires, tax, and installation cost $880. I am going to need to an alignment as well. The cost of having a car.
